PATENT OFFICE UNITED STATES,

1 Claim.

This invention relates to tobacco or smoking pipes and'has as its object the provision of a tobacco pipe wherein the bowl, stem, and mouth piece are separate and individual, one in respect to the otherso that the pipe may be readily disassembled for cleaning purposes even when the bowl contains burning tobacco.

Further, in accordance with the present invention, a tobacco pipe is provided with simple and efiicient means for trapping the tobacco juice in a manner to prevent the juice from being drawn through the smoke passages of the pipe stem and mouthpiece.

The invention, together with its numerous objects and advantages,. will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a longitudinal vertical sectional view 20 of a tobacco pipe embodying the features of the present invention. a

Figure 2 is a side elevational view of the stem.

Figure 3 is a vertical sectional view through the bowl and a portion of the stem associated therewith.

Figure 4 is an end elevational view of the stem.

Referring to the drawing by reference numerals it will be seen that the pipe includes, in general,.a bowl 5, stem 6, and mouthpiece '7.

In accordance with the present invention the bowl 5 has .a portion of the bottom thereof removed to accommodate one end portion of the stem 6. Stem 6, as shown, has a substantially reduced end '7 for engagement with the bowl 5 and extending through the stem from the end 7 thereof is a smoke passage 8. At the end thereof opposite to the end 7 the stem 6 is provided with a recess or socket 9 for receiving the pin or reduced end 10 of the stem '7 as clearly shown in Figure 1. Stem 7 as shown has of course a smoke passage leading therethrough and alining with the smoke passage 8 of the stem 6.

The end 7 of the stem 6 as before mentioned engages in the slot provided at the bottom of the bowl 5 and inwardly from the end '7 the stem is provided with a shoulder 11 to engage the exterior face of the bowl wall as shown.

End '7 has a reduced portion 12 reaching into and forming a part of the bowls interior surface, the edge of the stem at the end 12 being inclined for abutting engagement with the inclined face of the bottom wallof the bowl 5 as shown in Figure 1.

On' opposite longitudinal faces thereof, the end '7 for the full length thereof is provided with bacco juice,

grooves '13, while the inclined end face of the part 12 of the stem is also provided with a trans- I verse groove 14. The provision of thegrooves l3 and 14 reduces considerably the surfaces of the side and end faces of the stem end 7 which contact with the wall of the slot 15 which receives said end '7 of the stem. Further, the provision of such a groove provides between the contiguous faces of the stem end '7, and the walls of the slot 15 traps into which tobacco juice I will be likely to collect, thus reducing to a minimum the amount of such juice as would otherwise be sucked through the smoke passages of the stem 6 and'mouthpiece 7.

The cross sectional shape of stem end '7 and slot 15 will of course be complementaland in the present instance I have shown the walls of the slot 15 as having oppositely inclined upper and lower faces converging respectively at the. top and bottom of the slot while the sides of the stem end 7 are also provided with oppositely inclined upper and lower faces so as to enable the stem end '7 to be fitted snugly within the slot 15. To assemble the stem 6 and bowl 5 it will be apparent that the end '7 thereof is inserted lon- 30 gitudinally into the slot 15 until the inclined end of the part 12 of the stem end 7 abuts the inner end wall of the slot 15. Smoke from the bowl will of course be drawn through the smoke passages of stem 6 and mouthpiece '7 while, as before mentioned, the tobacco juices will have a tendency to seep between the contiguous faces of the stem end 7 and the walls of the slot 15 to accumulate in the grooves 15 where they are entrapped against being drawn into the mouth through the smoke passages of stem 6 and the mouthpiece '7. In the event that the smoke passage of the stem 6 becomes clogged with tobacco the end 7 of the stem may be readily withdrawn from the slot 15 and the smoke passage of the stem cleansed of all such accumulations of tobacco. It will thus be seen that a cleaning of the smoke passage of stem 6 can be readily affected without disturbing the contents of the bowl 5.

, What is claimed is:

In a tobacco pipe, a bowl having a slot in the bottom thereof, a stem forthe bowl having an end fitting snugly within said slot, said end of the stem having grooves in opposite side and end faces respectively thereof providing traps for to- CHARLES w. KNAPP.
